I gave you already "list oriented" respectively "set oriented" algorithms, which should be applicable for this new question too.  
See there ... [Moving part of TITLE to GENRE](https://community.mp3tag.de/t/16859/25)

But you can also apply standard functions, for example $strstr(x,y).

**TEMP1 \<== $ifgreater($strstr(%GENRE%' ','##02 '),0,'yes','no') TEMP2 \<== $ifgreater($strstr(%GENRE%' ','##51 '),0,'yes','no') TEMP3 \<== $ifgreater($strstr(%GENRE%' ','##52 '),0,'yes','no') TEMP4 \<== $ifgreater($strstr(%GENRE%' ','##53 '),0,'yes','no') TEMP5 \<== $ifgreater($strstr(%GENRE%' ','##54 '),0,'yes','no')**

**TEMP1 \<== $ifgreater($strstr(%GENRE%' ','##02 '),0,1,0) TEMP2 \<== $ifgreater($strstr(%GENRE%' ','##51 '),0,1,0) TEMP3 \<== $ifgreater($strstr(%GENRE%' ','##52 '),0,1,0) TEMP4 \<== $ifgreater($strstr(%GENRE%' ','##53 '),0,1,0) TEMP5 \<== $ifgreater($strstr(%GENRE%' ','##54 '),0,1,0) RESULT \<== $if($and(**
